Bill Gates & Warren Buffett To Build A New Kind Of Nuclear Reactor — Is That Good News?

Bill Gates and Warren Buffett want to build a new kind of nuclear reactor to generate electricity. Why? Because the wind doesn’t always blow and the sun doesn’t always shine. They intend to plunk their new toy down in the state of Wyoming on the former site of a coal-fired generating plant.

“This is our fastest and clearest course to becoming carbon negative,” says Wyoming’s governor Mark Gordon. “Nuclear power is clearly a part of my all-of-the-above strategy for energy.” Wyoming is the top coal producing state in America.

According to The Guardian, the new facility will be a joint venture between TerraPower, founded by Gates 15 years ago, and PacifiCorp, a Berkshire Hathaway-owned utility that serves customers in Wyoming, Idaho, Utah, California, Oregon, and Washington.

Small advanced reactors, which run on different fuels than traditional reactors, are regarded by some as a critical carbon-free technology that can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change. “We think Natrium will be a game-changer for the energy industry,” Gates told a media conference in Cheyenne, Wyoming this week.

345 Megawatts

The Guardian says the new generating station will produce 345 megawatts of electricity, but the output can be boosted by a molten salt energy storage component to 500 megawatts. The primary feature of the so-called Natrium technology is that it uses sodium to cool the reactor instead of water. Natrium is the Latin word for sodium, which is why its symbol on the periodic table of elements is Na.

Chris Levesque, TerraPower CEO, told the press this week the demonstration plant will cost about $1 billion and will take about seven years to build. “We need this kind of clean energy on the grid in the 2030s,” he told reporters. Actually, Chris, we need clean energy on the grid now, not 7+ years from now. A billion dollars would buy more than 500 MW of power and have it online, together with grid storage batteries, in a lot less time. Why wait?

Natrium Technology

I am not a nuclear engineer nor am I a rocket scientist, so I have to rely on Wikipedia to inform me about some things (I contribute $5 a month to support Wikipedia and encourage you to do the same).

Here is what I found out:

Advantages

The primary advantage of liquid metal coolants, such as liquid sodium, is that metal atoms are weak neutron moderators. Water is a much stronger neutron moderator because the hydrogen atoms found in water are much lighter than metal atoms, and therefore neutrons lose more energy in collisions with hydrogen atoms.

This makes it difficult to use water as a coolant for a fast reactor because the water tends to slow (moderate) the fast neutrons into thermal neutrons (though concepts for reduced moderation water reactors exist).

Another advantage of liquid sodium coolant is that sodium melts at 371K and boils / vaporizes at 1156K, a total temperature range of 785K between solid / frozen and gas / vapor states. By comparison, the liquid temperature range of water (between ice and gas) is just 100K at normal, sea-level atmospheric pressure conditions. Despite sodium’s low specific heat (as compared to water), this enables the absorption of significant heat in the liquid phase, even allowing for safety margins. Moreover, the high thermal conductivity of sodium effectively creates a reservoir of heat capacity which provides thermal inertia against overheating.

Sodium also need not be pressurized since its boiling point is much higher than the reactor’s operating temperature, and sodium does not corrode steel reactor parts.[2] The high temperatures reached by the coolant (the Phénix reactor outlet temperature was 560° C) permit a higher thermodynamic efficiency than in water-cooled reactors. The molten sodium, being electrically conductive, can also be pumped by electromagnetic pumps.

Disadvantages

A disadvantage of sodium is its chemical reactivity, which requires special precautions to prevent and suppress fires. If sodium comes into contact with water it reacts to produce sodium hydroxide and hydrogen, and the hydrogen burns when in contact with air.

This was the case at the Monju Nuclear Power Plant in a 1995 accident. In addition, neutron capture causes it to become radioactive; however, activated sodium has a half-life of only 15 hours. Another problem is sodium leaks which are regarded by a critic of fast reactors, M.V. Ramana, as “pretty much impossible to prevent.”

Fuel Used

Wikipedia adds that a natrium facility that generates less than 500 MW of electricity uses “uranium-plutonium-minor-actinide-zirconium metal alloy fuel, which is supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor.” I don’t know about you, but the words “uranium” and “plutonium” don’t sound like “different fuels compared to traditional nuclear reactors.”

The Guardian points out that nuclear power experts have warned that advanced reactors could have higher risks than conventional ones. Fuel for many advanced reactors would have to be enriched at a much higher rate than conventional fuel, meaning the fuel supply chain could be an attractive target for militants looking to create a crude nuclear weapon. And don’t even be concerned about Russian hackers. We know those malefactors only like to interrupt gasoline pipelines and beef processing plants. Pooty Poot and his henchmen would never stoop so low as to hack a nuclear power plant…would they?

People always rush to criticize Tesla for selling emissions credits, but no one wants to talk about the $80 million the US Department of Energy has already invested in TerraPower with millions more coming in the future. No one would expect Bill Gates and Warren Buffett — two of the richest white men in history — to foot the bill for their boondoggles all by themselves, would they?

All Of The Above

The key to understanding this story is found in Governor Gordon’s use of the words “all of the above.” That’s free market speak for “We’re happy to have a piddly little 350 MW facility of over here, just so long as we can continue supporting coal- and gas-powered generating plants that churn out hundreds of gigawatts over there.” In other words, it’s a smokescreen designed to allow fossil fuel interests to kick the can down the road a little further and add some greenwashing to their corporate portfolios at the same time.

Being rich does not necessarily make a person all that smart. America needs more nuclear power like a fish needs a bicycle. People in Wyoming may be fooled by this blather, but CleanTechnica readers aren’t taking the bait. Natrium was probably selected as the name of thus new nuclear technology because it sounds a little like “nature” or “natural.” That’s a great marketing ploy, but we’re not buying it. Frankly, the Bill and Warren show is more than a little disappointing.

Redditor: my Polestar 2 window stopped a bullet from hitting me [pictures]

This one’s pretty simple, kids – it’s exactly what it says on the tin: a Polestar 2 owner took to the Polestar subreddit this week claiming that the window glass in his new EV actually stopped a bullet from hitting him. Plus, he says he’s got the pictures to prove it. (!)

The brand may be evolving into its own, but the OG Polestar 1 and Polestar 2 were little more than hot electric versions of Volvo cars – and Volvo cars are known throughout the world for their secure, planted feel on the road and absolutely bananas high-tensile steel safety cages. As such, it should come as no surprise that the Polestar 2 is one of the safest sedans on the road today … but is the car really bulletproof?

That’s what one redditor is claiming after his window was hit by what they believed to be a stray bullet just five days after taking delivery.

Now, as the growing brand rivalry between Polestar fans and their Tesla-driving counterparts might lead you to expect, some of the comments are pretty pointedly referencing Tesla – and pretty funny. Here are a few of my favorites:

Now, that was fun, sure – but it’s worth noting that a number of commenters claiming alternately that there’s no way this was a .22 caliber bullet (certainly not a .22 WMR) or that it was a stray shot from very far away. The consensus seems to be that a .177 caliber air gun pellet is most likely to blame, but my money is on a small piece of stone or gravel kicked up at a weird angle from a nearby vehicle.

Regardless, it seems like CptMerica29 is A-OK, and their Polestar 2 hardly seems worse for wear, either. Here’s hoping it’s the last time we have to have a debate about what kind of bullet was being fired at an EV driver for a long time.

If you’d like to try your hand at driving a Polestar 2 through a volley of flying debris and other assorted projectiles and letting us know how you do, click the link below to score a great deal on one near you (while you still can):

Disclaimer

I would like to believe this is obvious, but there’s a “do not use batteries as toothpaste” sticker on this pack of Duracell batteries for a reason, so I’m going to err on the side of caution here and tell any of you reading the above and taking it seriously that: I am kidding. That was a joke.

To be clear, it is my position that NO VEHICLE this side of a Mercedes-Benz EQS GUARD or Inkas Armored S Class is actually bulletproof – and that, yes, a .22 is a real gun with plenty of lethal stopping power and, also yes, a pellet gun can and has killed a lot of people. DO NOT SHOOT AT CARS, and do not sit in your cars and let others shoot at you if you can at all avoid it.

Slate emerges with customizable EV pickup available for under $20k [Video]

Slate emerges with customizable EV pickup available for under $20k [Video]

After about a month of speculation and subtle hints from industry insiders, American EV startup Slate has emerged from stealth to share its flagship model with the world. This simplified all-electric pickup arrives with over 100 accessories, a five-seat SUV configuration kit, and get this… crank windows. Even better, this no-nonsense pedigree of EV is priced refreshingly low, starting below $20,000 after US tax incentives.

As we pointed out last month, there was much more we didn’t know than we could confirm about a new EV brand called Slate. The American automaker was verified as an official business on LinkedIn as of March 5, giving us a sparse trail of breadcrumbs to follow to learn more.

According to the page, Slate had already established a team of 200 to 500 employees, and 46 additional open roles were listed. Some open jobs, such as plant manager and suspension engineer, hinted that Slate has been working on at least one EV.

Aside from promising “the next generation of innovation in the industry” (despite not confirming what industry), Slate’s website stated that we would learn more on April 24. We had heard rumblings that the Troy, Michigan-based startup was on the cusp of debuting a simple, all-electric pickup.

However, that wasn’t confirmed until two days ago, when the first real-world images of the EV emerged ahead of Tesla’s earnings call. Our readers pointed out that “Slate” is an anagram of “Tesla,” which offers interesting fodder to the conspiracy theory scene at best.

While Slate’s name may be a tongue-in-cheek nod to reimagining an EV industry Tesla championed early on, the name seems more rooted in the fellow American company’s clean slate approach to EV design. From what we’ve now seen, Slate is breaking from the trend of other startups kicking off market entry with top-tier, luxe models starting in the $80-$100k range.

Instead, it has created a no-nonsense EV pickup that starts at a super low price, leaving the upgrades and customizations to the customer. Better still, if you US customers prefer a five-seat option, Slate also offers that. See below:

Slate debuts EV that can be 2-seat pickup or 5-seat SUV

Slate has officially arrived and, in my opinion, is a welcome breath of fresh air (because of no emissions, of course) to an American EV industry that is growing by the day, but has yet to reach critical mass in adoption.

Much of that struggle relates to pricing (not to mention lackluster local charging infrastructure). Most EVs are not affordable enough for the average consumer yet, and to get an electric pickup like Slate is now offering, for example, you have to opt for a model from Ford, GM, or Rivian that will cost at least $63,000 and will easily go up from there with added features like range.

Instead of coming out swinging against the big boys, Slate has dug itself a nice little niche in simplified affordable EVs that are modular and customizable. Slate’s first CEO, Chris Barman, elaborated:

The definition of what’s affordable is broken. Slate exists to put the power back in the hands of customers who have been ignored by the auto industry. It is a radical truck platform so customizable that it can transform from a 2-seat pickup to a 5-seat SUV.

Steel wheels, HVAC knobs, and crank windows – Slate is most certainly taking a clever approach to affordable US EVs for all. Designed to be “approachable and timeless,” the startup flagship model is truly a black slate canvas that puts the brush in the hands of its customers.

The company shared it will offer over 100 accessories, available a la carte or in a bundle, available from your initial order or years down the road. The dash also includes a universal phone mount with USB power, enabling you to use whatever smart device and OS you’d like. Have it custom wrapped by the Slate team or do it yourself, Slate is not only offering variety to customization, but also the process by which it is achieved.

Another example is Slate’s flat pack SUV Kit, which turns the EV pickup into a 5-seat SUV, complete with a roll cage, airbags, and rear seat. Again, you’ll have the choice to have Slate integrate it in Michigan or do it yourself, adding a bit of a DIY “gearhead” philosophy the EV segment has lacked since day one.

According to Slate, its flagship EV will be sold directly to consumers and is available to reserve now with a $50 deposit. The trucks will be built in the US and start at an MSRP below $20,000 (after federal tax incentives). No timeline on when production may begin, but a representative for Slate told Electrek that initial customer deliveries are… slated to begin in Q4 2026. Not too shabby.

While we await more details regarding this new American brand, here’s a better look at Slate’s first EV from a video it provided below:
